Oil Content and Fatty Acid Profile of some Pine Nuts Species (Pinus spp.) [PDF]

open access: yesJournal of Nuts, 2019
The pine nuts, as the most expensive ones, are a source of healthy oil. Accordingly, the hypothesis was genetic differences of pine species (Pinus spp.) affect their nut oil content and fatty acid phytovariability.

Ecological and morphological studies in the hybrid zone between Pinus sibirica and Pinus pumila

open access: yesAnnals of Forest Research, 2013
In the Baikal Region, there is no phenological isolation between Siberian stone pine (P. sibirica Du Tour) and Siberian dwarf stone pine (P. pumila (Pall.) Regel) since the timing of their 'flowering' coincides.

30-year cone production dynamics in Siberian stone pine (Pinus sibirica) in the southern boreal zone: a causal interpretation [PDF]

open access: yesPlant Ecology and Evolution, 2021
Background and aims – Siberian stone pine is a keystone species for Siberia, and numerous studies have analyzed Siberian stone pine seeding dynamics in connection with the dynamics of weather conditions.

Photosynthesis and respiration in the needles of Pinus sibirica and Pinus pumila and their putative hybrids

open access: yesAnnals of Forest Research, 2013
A putative interspecific hybridization in Pinaceae family was investigated. Very rarely the physiological methods were involved in hybridization processes that occurs in the hybrid zones.

Tree rings as an ecological indicator of the reaction of Swiss stone pine (Pinus cembra L.) to climate change and disturbance regime in the extreme environment of cliff forests

open access: yesEcological Indicators, 2023
Tree rings are an ecological indicator, useful for studying the adaptation of trees in a changing environment, especially in the unique habitat of high-elevation cliff forests.

Spatial Niche Segregation of Sympatric Stone Marten and Pine Marten--Avoidance of Competition or Selection of Optimal Habitat? [PDF]

open access: yesPLoS ONE, 2015
Coexistence of ecologically similar species relies on differences in one or more dimensions of their ecological niches, such as space, time and resources in diel and/or seasonal scales. However, niche differentiation may result from other mechanisms such

Different increase rate in body mass of two marten species due to climate warming potentially reinforces interspecific competition

open access: yesScientific Reports, 2021
Many species show spatial variation in body size, often associated with climatic patterns. Studying species with contrasting geographical patterns related to climate might help elucidate the role of different drivers. We analysed changes in the body mass

Assessing Pinus pinea L. resilience to three consecutive droughts in central-western Italian Peninsula

open access: yesiForest - Biogeosciences and Forestry, 2020
Climate projections for the Mediterranean area forecast drier and hotter conditions and increasing trend in extreme climatic events such as drought. Scientific evidences reported that extreme dry spells affected the stem growth of different Mediterranean

Ecological and morphological studies in the hybrid zone between Pinus sibirica and Pinus pumila [PDF]

open access: yesAnnals of Forest Research, 2008
In the Baikal Region, there is no phenological isolation between Siberian stone pine (P. sibirica Du Tour) and Siberian dwarf stone pine (P. pumila (Pall.)Regel) since the timing of their 'flowering' coincides.

Selective forest health felling in protective Siberian stone pine stands of Khakassia: an experience of post-logging survey and silvicultural analysis [PDF]

open access: yesСибирский лесной журнал, 2021
On the example of three areas of protective Siberian stone pine Pinus sibirica Du Tour stands of Khakassia, the expediency of selective forest health felling is considered. Forest growing conditions on the plots are favorable for dark coniferous Siberian
